摘要：
An ablation catheter includes a flexible shaft having length sufficient to access a patients renal artery. An electrode arrangement is provided at the distal end of the shaft. A handle unit includes a housing configured for hand-held manipulation and is coupled to the catheter. A battery and one or both of a high frequency AC generator and ultrasound generator are provided in the housing. The battery serves as the sole source of power for the generator. The generator is configured to generate energy sufficient to ablate perivascular renal nerve tissue using energy stored in the battery. The catheter may be disposable and the housing re-usable. Both the catheter and the housing may be disposable.
